Quantum Chromodynamics

This text is an introduction to theoretical physics, providing necessary mathematical tools together with examples and worked problems. In introductory chapters, the reader becomes familiar with the hadron spectrum, while the SU(N) symmetry groups and the relativistic field theory are briefly recapitulated; then a discussion of scalar quantum electrodynamics and scattering reactions follow before gauge quark-quark interactions, pertubational QCD, renormalization groups, and tests of pertubational QCD are treated in detail. Chapters on non-pertubational QCD and quasi-phenomenological applications conclude the text.
